Gambling addiction, also known as problem gambling or ludomania, is a serious issue that can lead to other addictions, depression, and of course, financial ruin.

Gambling hits the same receptors in your brain as cocaine. Support groups such as Gamblers Anonymous can be beneficial in providing support and abstinence.
